Abstract:In order to better study the blasting mechanism,to understanding the blasting effect of cut blasting in the process of roadway drivage. This article take the blasting process of two sections cut hole with reverse detonation for example,using the finite element software ANSYS/LS-DYNA on blasting cavity expansion process numerical simulation,get the blasting cavity formation process,Clearly show in different moments of stress, deformation, blasting technology for further optimization and experiments provide a certain basis.

Abstract:Based on the existing research results in the explosive composite areas at home and abroad, this paper summarizes the research status of explosive composite from the aspects of explosion composite technology, the composite explosive, explosion mechanism of composite, the complex numerical simulation, and points out of some problems existing in the composite, prospects the future development direction of explosive composite field.
